Anterior Dislocation of the Tibiofibular Joint: A Case Report.

Dislocation of the proximal tibiofibular joint (PTJ) is a knee injury that occurs infrequently. In this case, the dislocation of the PJT of the right knee was reported with subsequent pain and limitation in range of motion, caused by trauma during the practice of a soccer game. An intense pain was observed in the area where the head of the fibula is located without finding crepitation or deformity. Initially, comparative anteroposterior and lateral X-rays of the knees were requested, showing proximal tibiofibular joint incongruity with anterolateral displacement without evidence of fracture lines. For this reason, it was decided to take a tomography of the right knee that confirmed the presence of anterior dislocation of the proximal tibiofibular joint. Closed reduction under sedation was scheduled.

Escalas de percepción subjetiva del esfuerzo y actividad física en tiempos de SARS-CoV-2/COVID-19 / Scales of subjective perception of effort and physical activity in times of SARS-CoV2/COVID 19

Sr. Editor; recientemente leímos con interés el artículo publicado en la Revista Universidad y Salud en su volumen 22, número 2, denominado "Recomendaciones prácticas para evitar el desacondicionamiento físico durante el confinamiento por pandemia asociada a COVID-19."(1). Felicitamos a los autores por el gran valor y alta pertinencia del artículo en general, cuyos resultados contribuyen a elevar el nivel de conocimiento respecto a recomendaciones prácticas para evitar el sedentarismo asociado a las medidas de confinamiento por SARS-CoV-2/COVID-19. Sin embargo, con el fin de aportar mayor e importante información nos gustaría exponer algunas reflexiones centradas en las recomendaciones de actividad física (AF).

Recomendaciones prácticas para evitar el desacondicionamiento físico durante el confinamiento por pandemia asociada a COVID-19 / Practical recommendations to avoid physical deconditioning during confinement due to pandemic associated with COVID-19

Introducción: El aislamiento social durante la pandemia por COVID-19 incluye el confinamiento en casa, que redunda en incremento de la inactividad física y de comportamientos sedentarios, favoreciendo el desacondicionamiento físico. Las personas desacondicionadas físicamente tienen alteraciones metabólicas y sistémicas por la falta de movimiento. Objetivo: Presentar recomendaciones prácticas, y de bajo costo sobre actividades basadas en la evidencia para evitar el desacondicionamiento físico durante el confinamiento en casa, que se pueden mantener a largo plazo, incluso después de la pandemia. Materiales y métodos: Revisión documental sobre estrategias para conducir estilos de vida saludable en casa que disminuyan los efectos negativos a nivel fisiológico producidos por el confinamiento derivado de la pandemia. Resultados: La evidencia señala que el confinamiento en casa incrementa los niveles de inactividad física y el comportamiento sedentario; la realización de actividad física bajo condiciones particulares puede entre otros, fortalecer el sistema respiratorio e inmunológico, mantener la condición física y generar efectos positivos sobre la salud mental. Conclusiones: Los hábitos relacionados con la práctica de actividad física en casa se deben mantener en el tiempo, se recomienda realizarla de manera programada, establecer horarios de descanso entre las actividades y durante la noche, y elegir aquellas que generen disfrute.

Introduction: Social isolation during the COVID-19 pandemic includes home confinement, which results in increased physical inactivity and sedentary behaviors, favoring physical deconditioning. Deconditioned people have metabolic and systemic disorders due to the lack of movement. Objective: To present practical, low-cost recommendations on evidence-based activities to avoid physical deconditioning during home confinement, which can be maintained over the long term, even after the pandemic. Materials and methods: Documentary review on strategies to support healthy lifestyles at home that decrease the negative effects at a physiological level produced by the confinement derived from the pandemic. Results: Evidence indicates that home confinement increases the levels of physical inactivity and sedentary behavior; executing physical activity under particular conditions, among other effects, can strengthen the respiratory and immune systems, maintain physical condition and generate positive effects on mental health. Conclusions: The habits related to the practice of physical activity at home should be maintained over time, it is recommended to do it on a scheduled basis, define rest times between activities and during the night, and choosing those that generate enjoyment.

Pasteurella multocida: a nightmare for a replaced joint and the challenge to save it.

Pasteurella multocida a small gram-negative coccobacilli is primarily found as normal flora of cats and dogs. These organisms can cause a variety of infections in humans, usually the result of scratches, bites and licks by percutaneous inoculation of the organism. Most cases of septic arthritis involve a cat or dog bite distal to the involved joint without direct penetrating injury to the joint. On scenarios were Pasteurella infection is suspected within a prosthetic joint, aggressive surgical debridement and/or removal of the prosthesis with intravenous antibiotics is recommended. Prosthetic joint infections secondary to animal bites are an extremely rare complication and few cases have been reported in the literature. This is a case report of a patient that suffered a cat's bite of his right prosthetic knee and against all odd was able to save it without surgical intervention.

Just a flare---the Pandora's box approach.

Systemic lupus erythematosus is a chronic inflammatory autoimmune disease characterized by autoantibodies specific for highly conserved nuclear antigens, such as double-stranded DNA, histones and ribonuclear proteins. The course of the disease is unpredictable and nine times more common in females. Among the neurological manifestations of collagen vascular diseases is the most commonly recognized and better studied disease. Central nervous system lupus is a serious and potentially treatable illness presenting as difficult diagnostic challenge. This is a case report of a patient that suffered central nervous system manifestations of severe active lupus. Early recognition of this entity is essential to expedite appropriate to treatment and avoid future complications.
